The end of the year means the end of the lunar calendar. In the old society, people who owed rent and were heavily in debt had to pay their debts at this time. Chinese New Year is just like customs clearance, so it is called the Year Pass.

During People's Republic of China (PRC) (China), a large-scale phenomenon of high traffic pressure appeared around the Lunar New Year, namely "Spring Festival travel rush Peak". Centered on the Spring Festival, it takes about 40 days.

During the "Spring Festival travel rush Peak", a large number of migrant workers went home for the New Year. Due to the lack of transportation capacity, one ticket is hard to find, and scalping is even worse.

Precautions:

Headed by the centennial festival, the Spring Festival is the most solemn traditional festival of the Chinese nation. Influenced by China culture, some countries and regions in the world also have the custom of celebrating the Spring Festival. According to incomplete statistics, nearly 20 countries and regions have designated the Spring Festival in China as a legal holiday in all or part of the cities under their jurisdiction.

Spring Festival, Tomb-Sweeping Day, Dragon Boat Festival and Mid-Autumn Festival are also called the four traditional festivals in China. The folk custom of Spring Festival was approved by the State Council to be included in the first batch of national intangible cultural heritage list.
